Ever Wondered What A Black Hole Opening Up Over Earth Would Look Like?
Picture the scene, it's 1am, you're making your way home from the pub, you're a bit pissed. Suddenly, the sky lights up, you look up and you see this:
A black hole opening above the Earth. It's fair to say, you'd have that feeling that your bowels are about to empty.
This clip, which was uploaded to YouTube, is based on scientific theories of how the black hole would look if Earth was in the centre of the Milky Way.
Luckily for us, black holes don't wander about the universe looking for stuff to suck up. The orbit of a black hole would need to be very close to the solar system to affect us on Earth, so that's a relief.
However, if one did suddenly open up near to Earth, we would
experience a huge gamma-ray-burst and be hit with deadly levels of radiations.
Black holes are hard to study, because no light can escape, so they're invisible. Instead, scientists and astronomers observe the behaviour of things close by to see the effects of the black hole.

According to NASA, some black holes form when a star collapses in on itself. Our sun is too small to turn into a black hole, when it does eventually burn out it will instead become a red giant star.
Other black holes, called supermassive black holes, are believed to be at the centre of every large galaxy in the universe and are thought to have been created at the same time as the universe.
The one at the centre of the Milky Way is called Sagittarius A* and it has a mass equal to about four million suns, but it would fit inside a ball around the same size as the sun.
OK, that's enough science for one day. My head hurts.
